上田市における3歳児健康診査での眼科検診

Ophthalmological examinations during a health-check program for three-year-old children in Ueda City

要約　目的：上田市で実施した3歳児健康診査での眼科検診の報告。対象と方法：2008年度に該当者1,492名のうち1,337名（89.6％）が受診した。彼らについて眼位，眼球運動，他覚的屈折を視能訓練士が検査した。結果：検査不能の9名を除き，60名（4.5％）で精査が必要と判定された。内訳は屈折異常が44名，斜視の疑いが16名であった。レチノマックス^®で測定した2,108眼での等価球面度数は－1.79±1.40Dであり，FR-5000^®で測定した386眼では＋0.47±0.72Dであった。乱視度数は前者では0.50±0.56D，後者では0.54±0.34Dであった。レチノマックス^®では4.3％に＋1.0D以上の遠視または2.0D以上の乱視があった。FR-5000^®では4.7％に＋2.0D以上の遠視または2.0D以上の乱視があった。結論：3歳児健康診査での眼科検診を行うことで，屈折異常または斜視を早期に発見できた。

Abstract.　Purpose：To report the outcome of ophthalmological examinations during a routine health-check program for 3-year-old children in the City of Ueda in Central Japan. Cases and Method：A total of 1,337 3-year-olds joined the program. They were evaluated for ocular position,eye movement,and refraction by optometrist. Results：Nine cases failed to co-operate and could not be examined. Sixty cases were assigned to further examinations. They comprised 44 cases with refractive error and 16 cases with suspected strabismus. Refraction examined by Retinomax^® averaged－1.79±1.40D in 2,108 eyes and that by FR-5000^® averaged＋0.47 ±0.72D in 386 eyes. Astigmatism averaged 0.50±0.56D by Retinomax^® and 0.54±0.34D by FR-5000^®. Examination by Retinomax^® showed hypermetropia by ＋1.0D or greater or astigmatism by ＋2.0D in 4.3％ of cases. Examination by FR-5000^® showed hypermetropia by ＋2.0D or greater or astigmatism by ＋2.0D in 4.7％ of cases. Conclusion：Early detection of refractive error or strabismus was possible during a health-check program for 3-year-old children.
